日落黄制备

(1)日落黄的制备。 把对氨基苯磺酸加入11-12,然后慢慢加入碳酸钠使其完全溶解,过滤;冷却至0-5℃,再加入对氨基苯磺酸1.5-1.8倍量(质量)的盐酸,搅匀静置,析出细微的1-萘胺-4-磺酸结晶,并冷却至5℃以下。在3-5℃下缓慢加入1:2(质量)的亚硝酸钠溶液进行重氮化,得重氮液。反应完毕后料液对刚果红试纸呈强酸性(显蓝色)。
将2-萘酚-6-磺酸钠搅拌溶解于20倍量(质量)75-80℃的水中,再加入部分碳酸钠(总量的1/5),溶解后过滤。滤液投入反应釜,然后加入其余的碳酸钠,搅拌冷却至5-8℃;再在10-15℃和PH8-9时,缓缓加入重氮液进行偶合反应数小时。
反应完毕后(2-萘酚-6,8-二磺酸钠略为过量),将其升温至50-60℃,加入精制氯化钠,搅拌,将其自然冷却至室温,静置析出结晶;将结晶搅拌溶解于15倍量(质量)70℃的洁净水中,加入适量的碳酸钠,使溶液呈微碱性,过滤后加入精盐,搅拌并用盐酸调pH至6.5-7.0。静置、结晶、分离、干燥得成品。
(2)日落黄铝色淀的制备。 由氯化铝、硫酸铝等铝盐与碳酸钠等碱类制取氢氧化铝,然后添加于日落黄水溶液,沉淀而得产品。 3. 由对氨基苯磺酸重氮化后,在碱性条件下与2-萘酚-6-磺酸偶合,用食盐将生成的色素析出,过滤,精制即可。
